Why do fluorescent lamps make sounds?

What is buzzing is the sound of ballast. Electromagnetic induction vibrates the coil in the ballast and drives the sound of its shell.

What I scoff at is the sound of current in the lamp. This sound shows that your lamp is aging ~ it's almost time to change it ~

BOBO's electromagnetic sound is the sound that the air around the lamp vibrates due to the instantaneous electromagnetic change when the lamp is just started ~ just like the principle of thunder.
